Mastering PhoneGap Mobile Application Development

By: Kerri Shotts

Overview of this book

PhoneGap is a useful and flexible tool that enables you to create complex hybrid applications for mobile platforms. In addition to the core technology, there is a large and vibrant community that creates third-party plugins that can take your app to the next level. This book will guide you through the process of creating a complex data-driven hybrid mobile application using PhoneGap, web technologies, and third-party plugins. A good foundation is critical, so you will learn how to create a useful workflow to make development easier. From there, the next version of JavaScript (ES6) and the CSS pre-processor SASS are introduced as a way to simplify creating the look of the mobile application. Responsive design techniques are also covered, including the flexbox layout module. As many apps are data-driven, you'll build an application throughout the course of the book that relies upon IndexedDB and SQLite. You'll also download additional content and address how to handle in-app purchases. Furthermore, you’ll build your own customized plugins for your particular use case. When the app is complete, the book will guide you through the steps necessary to submit your app to the Google Play and Apple iTunes stores.

That said, it's important to recognize a very important fact about Sass, which makes it easier to learn: every CSS file is a valid SCSS file. Sass itself understands two formats; but the format we'll be using is similar to the CSS syntax and uses the .scss extension. This means that you can write pure CSS and Sass will recognize it without a problem. This allows you to learn features at your own rate without losing productivity. In cases where you don't know a Sass feature, you can write regular CSS. Later, when you've learned more, you can rewrite the CSS using Sass.

Note

The other format that Sass understands uses indentation rather than brackets in order to define the structure of the file. These files use the .sass extension.

Before we delve deeper into the benefits of Sass, it is important to remember that browsers don't support the SCSS syntax. This means that...
